Esophageal atresia is the interruption of the tubular esophagus. Its incidence is 1 in 2,000-4,000 live births. It is associated with the VACTERL disorders. The most common associated anomaly is the tracheoesophageal fistula. Symptoms include drooling due to accumulation of pharyngeal secretions, regurgitation of ingested fluids and frothy sputum. Infants present shortly after birth.

Contrast collecting in proximal esophageal pouch. A contrast study of the pouch is rarely indicated. Air injected through the NG tube can be used as very safe, negative contrast agent.
